lBe it known that ,L Tnnononn H. Hanna- KonN,a citizen of the United-States, reslding atI Denver, in the county of Denver and.l

State of Colorado, have invented certain new and useful Improvements in Gra tion of the invention, such as will enable others skilled in the art to whichl it appertains to make and use the same'.

` This invention relates to' new and useful improvements in gaseous fuel heaters, and

mixers for combustion engines andmore particularly to such a device foruse on automobile engines, the primary object of the 1nvention being to provide-a device whereby kerosene distillate or any other inferior oil Ina-y'lbe used in place of gasolene which is usually used. in devices of. this character.

A further object of the invention resides in providing a device which will enable the explosive mixture, to be formed instantaneously and which'resulting gas will be equally as, if not more, powerful vthan gasolene which is now used in explosive engines and afurther object resides in providing such a device in connection withthe exhaust pipe of the engine whereby 'the heat thereof will be utilized in the compounding ofthe oil and air into explosive gas.

Still another object of the-invention resides in providing a twistedyand perforated strip through which the oil and air are l-' rected,s1 1ch strip being disposed ina housing wlthin the exhaustpipe of the engine.

vandA more particularly pointed out in 3the view of a gas engine with my invention applied Fig; 2 is a vertical'section taken along the line 2 2 of Fig. 1.

4.l'n describing the invention 4ll shall refer to the drawings in which similar reference characters designate corresponding parte throughout `the several views and in' which Specification of Letters Patent.. rapimenti-tn med' tenait, 1am. serial no. 'attesa seous- Fuel Heaters and Mixers for Internal-Com-l bustion Engines; and ll do declare the following to be a full, clear, and exact descrip- Patented ll une -22, ilhjl.

I 1? designates an internal 'combustion-engine consisting of a plurality of cylinders, l having vshown four in number but any.v number may be provided, and connected to'said cyl- 60 inders inthe usual or any manner is an exhaust' pipe 2,. ln orderl to facilitate my invention, this pipe 2 isV preferably formed in sections removably secured together, said sections beingl designated in the drawing as 65 2a and 2. At the junction of the vsections A l of this exhaust pipe, .the latter is slightly en- -la-rged in diameter and at diametrically opposite points thereon said pipe is provided4 with threadedl openingsindicated as-3 and 70 4f, respectively:` @Engaged with the threaded' opening 3, which, as shown in the drawing, is at the lowen' portion of the pipe 2, is an intake pipe 5' which leadsfrom acarbureter 6, thelatterbeing one of any approved type. 75 p Mounted in connection with the carbureter 6 is a'valve casing 7 in which is arranged a three-way' valteA 8- and leading to the casing 7`.are the supply pipes 9 and 1 0; The pipe' 10 leads toa source of gasolene supply 8o .which is provided for use 'in starting the motor while the pipe. 9' leads to a kerosene or distillate supply. The valve has a crank arm '1 1 connected with one end thereof and pivotahy connectedl to the outer end of the 85 cranl'r"'-.armfis an actuating rod 12 which leads to any remote point whereby the 'valve v8 may be actuated as desired. The use of thisva'lvefor the purpose of permitting gasolene ico-'flow to the carbureter and thence 90 to the cylinders will be hereinafter and more particularly referred to.

l`flmnected with lthe threaded opening' 4 which is opposed' to' vthe threaded opening 3 with' which the' pipe t5y is connected, is a te, pipe sectionl 13 which leads ,directly to the 'manifold of the engine whereby to supply the latter with-the explosive mixture winch is formed in a' ,manner to be presently described. .Gast within' the enlarged portion H00 of the Aexhaust. pipe 2 at the fend Aof the section' 2 thereof are the centrally' converging elbow sections 14 and llwhich connect respectively with the openings 3 and 4. These elbows cm'mtinuing from the opemngs 1l05 3 and' 4 are vi e d towardthe section 2" and are internally threaded at their ends as; shownat 16. Eged with these threaded cnd's 16 of the velbow sections are the tubular members or pipe sections 17-wh1ch ex- M0 tend longitudinally within said section 2"- 'lhe outer ends'efsaid tubular members 17 are externally threaded and engaged with the threaded ends of a U-shaped bend or union 18 which thus forms a U-shaped casing or housing within the one section ofthe exhaust pipe. The walls of the members 17 and 18 are spaced from the walls of the exhaust pipe lso that the products of combustion may readily pass through the latter but it will be appreciated that by so doing said sections 17 and 18 will be thoroughly heated. 1

Disposed in each of the arms'of this U- shaped member or in other` words disposed in each of said members 17 isv a twisted and perforated strip'19. The stripin one of the sections 17 is twisted to the right and the other is twistedto the left which enables oil and air passing therethrough to ber thoroughly compounded into gas as will appear ater.

This invention primarily contemplates the provision of a mea-ns for forming gas from A oils other than gasolene in order to decrease the expense connected with the running of an internal combustion engine and also to increase the power. In accomplishing this result, my invention also contemplates .the using of kerosene, distillate and other inferior oils. as above stated, but inasmuch as the use of such inferior oils requires a certain amount of heat in order to form a perfect gas, I desire to vuse my invention in connection with the exhaust pipe of the engine' so that the necessity for providing some other heating means is obviated. Under such conditions, it will be seen that lthe engine must be in operation in order to supply such heat to the exhaust pipe and. of course, gasolene must be used in the starting of the engine.

In the operation of the device, the valve i8 is first operated so as to permit a supply of gasolene to flow to the carbureter 6 whereupon the engine may be started in the usual manner and after running for a shorttl'in'e, the products of combustion exhaustingr through the pipe 2 will thoroughly. heat the various members disposed therewithin. The valves may then be disposed so as to cut off thesupply of gasolene and permit the oil, such as kerosene, to iiow tothe carbureter.

the carbureter will, upon the suction stroke ofthe piston form a'mixture as is done with the use of gasolene. The oil mixed with the air. however. will be directed first through the intake-pipe and through the elbow 14 to thesection'l'? where said mixture 'is forced the invention.

in the mixture will be thoroughly heated and a perfect explosive gas will thus vbe compounded.` This gas after leaving the last mentioned section 17 is directed through the pipe 13 from which point it is conveyed to the manifold of the engine to be distributed to the cylinders in 'any approved manner.

From the foregoing it will be seen, that I have provided a Simple, inexpensive and elicient meansY for carrying out the objects of the invention and while I have particularly described the elements best adapted to perform the functions set forth it is obvious that various changes in the form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from Athe spirit or sacrificing any of the principles of Having thus described my invention, what I claim is;
